No, H2CO3 is an aquous solution of carbon dioxide gas (CO2). It can also be 'written' as (CO2+H2O) or (CO2.H2O) or (CO2,aq) = hydrate of carbon dioxide and its chemical name â¦ : carbonic acid.hat we call carbonic acid is actually CO2 dissolved in water in equilibrium with H+ and HCO3^-. Carbonic acid is a weak acid, and so you might think that there would be nonionized H2CO3 molecules.
When this compound comes in contact with water or moist air, it is decomposed and phosphine (PH3) is formed. This is a toxic compound, and it is also very flammable in air. Magnesium is mainly present as Mg2+ (aq) in watery solutions, but also as MgOH+ (aq) and Mg(OH)2 (aq). In seawater it can also be found as MgSO4. Water solubility of magnesium hydroxide is 12 mg/L. Other magnesium compounds are clearly more water soluble, for example magnesium carbonate (600 mg/L). Magnesium sulphate adds a bitter flavour to water, and has a water solubility of 309 g/L at 10oC.
